Epistaxis explained by Dr. Busti. In this episode on This Is Why, we break down why epistaxis happens, how clinicians think through causes of bleeding, and why the location of bleeding matters clinically.

Dr. Busti explains anterior vs posterior epistaxis, common risk factors, medication-related bleeding, vascular anatomy, and when recurrent nosebleeds may signal a more serious underlying condition.
